Yes, it's possible. I've created a simple example, using dynamic geometry. I use browser local storage to save cnanged geometry, but you should use server requests.The application remembers the latest geometry data and save it. When you open the app again, it sets the geometry from memory.

I think, you should use JavaScript code to send requests and check they, if you need. The Node Logic Editor can create only simple logic.Just replace code lines, where m_stor module is used, by server requests. In this case, you can check request states.
